A crane is a type of machinery designed to lift and move heavy loads. It typically consists of key parts, including a hoist, mast, trolley, and boom. Jib cranes specifically utilize a rotating arm to handle materials. In this research, a jib crane’s boom is analyzed through finite element analysis (FEA) using ANSYS software. A standard cantilever steel I-beam ( S10@31.8  lb/ft) with a span of 4 meters is examined to assess its buckling behavior, including factors like maximum principal stress, maximum shear stress, and equivalent stress under its own weight and a vertical load applied at the free end. Moreover, 20 models of trapezoidal corrugated web beams differing in corrugation angles, web widths, and corrugation plate lengths are designed in AutoCAD and analyzed in ANSYS to evaluate their lateral-torsional buckling under similar load conditions. The analysis shows that the length of the corrugated plate, web width, and corrugation angle affect the beam’s resistance to buckling. In comparison to flat web beams, the corrugated web beams offer better resistance to buckling while maintaining similar weight.
